How to Forward Calls on iPhone: Complete Step-by-Step Guide


Need to redirect incoming calls to another number? You're not alone—millions of iPhone users set up call forwarding for work travel, phone repairs, or juggling multiple devices. Here's everything you need to know to get it done in minutes.
What Is iPhone Call Forwarding and Why You Need It
Call forwarding on your iPhone automatically redirects incoming calls to another phone number you specify. When someone dials your iPhone, the call routes to your chosen destination—whether that's your home phone, work line, or colleague's device.
Here's why people love this feature:
Never miss important calls during meetings or travel
Keep one number active while switching between devices
Share call responsibilities with team members or family
Avoid international roaming charges by forwarding to local numbers
💡 Unlike other smartphone features, call forwarding happens through your carrier's network, not your iPhone's settings. This means it works even when your phone is dead or out of service.
How to Call Forward on iPhone: 4 Simple Methods
Method 1: Phone Codes (Fastest Option)
This method works with most carriers and takes less than 60 seconds. Here's how it works:
To turn on call forwarding:
- Open your Phone app
- Dial *72 followed by the 10-digit number (no spaces)
- Press the call button
- Wait for a confirmation beep or message
To turn off call forwarding:
- Dial *73
- Press call
- Listen for confirmation
To check if it's working:
- Dial *72# and press call
- Your carrier sends a text or voice message with the status
📝 Some carriers use different codes. T-Mobile users might need *21* instead of *72. If the standard codes don't work, try calling your carrier's customer service.
Method 2: Using iPhone Settings (If Supported by Your Carrier)
Some iPhone users see a Call Forwarding option under Settings → Apps → Phone → Call Forwarding.
Here's how:
- Go to Settings → Apps → Phone → Call Forwarding
- Toggle on Call Forwarding
- Tap "Forward To" and enter the number
- Tap Back to save
⚠️ This option only appears if your carrier supports GSM call forwarding. It usually only sets unconditional forwarding (all calls). For conditional options (busy, unreachable), use carrier codes or apps.

Method 3: Carrier Apps (Advanced Control)
Most major carriers offer call forwarding through their apps. This method gives you more control over when and how calls get forwarded.
For Verizon users:
- Open the My Verizon app
- Go to Account → Manage Products & Apps
- Select Call Forwarding
- Enter your forwarding number and save
For AT&T users:
- Open the myAT&T app
- Navigate to Manage Features
- Choose Call Forwarding
- Set up your preferences
For T-Mobile users:
- Open the T-Mobile app
- Go to Account → Line Settings
- Select Call Forwarding
- Configure your settings
Why use the app method? You get options like forwarding only when busy, setting different numbers for different times, and managing multiple forwarding rules.
Method 4: Customer Service (Full Support)
When all else fails, your carrier's customer service can set everything up for you.
- Call your carrier's customer service number
- Say "call forwarding" when prompted
- Provide the representative with your forwarding number
- Ask them to confirm it's working
This method works best if you have questions about pricing or need help with complex forwarding rules.
Call Forwarding Costs (What You'll Actually Pay)
Here's the reality about call forwarding costs:
Monthly fees by carrier:
- Verizon: $5-10/month depending on your plan
- AT&T: Free on unlimited plans, $5/month on others
- T-Mobile: Free on most current plans
- Smaller carriers: $3-15/month typically
💰 Check if your current plan already includes call forwarding. Many unlimited plans offer it free, but you might need to activate it first.
International forwarding warning: Forwarding calls to international numbers can cost $20+ monthly, plus you'll pay international rates for each call. Consider alternatives like Google Voice for overseas forwarding.
Smart Alternatives When Standard Forwarding Isn't Right
Sometimes traditional call forwarding doesn't fit your needs. Here are smart alternatives:
Google Voice (Free Option)
Think of Google Voice as a virtual phone number that can ring multiple devices at once.
How it works:
- Sign up for a free Google Voice number
- Give people your Google Voice number instead of your iPhone number
- Configure it to ring your iPhone and any other numbers simultaneously
Best for: People who want more control and don't mind using a different phone number.
Dual SIM Setup (iPhone XS and Newer)
If you have a newer iPhone, you can use two phone numbers simultaneously.
How it helps: Keep your main number active while using a second SIM for specific situations or contacts.
Best for: Business users who need separate work and personal numbers.
Troubleshooting Common Call Forwarding Problems
Problem | What's Happening | Quick Fixes |
---|---|---|
Call Forwarding Not Working | Your calls aren't going to the forwarding number | Check your plan (some prepaid plans exclude call forwarding) > Verify account balance > Restart your iPhone > Test with another phone (have someone call to confirm) |
Incoming Calls Going to Voicemail | Calls skip forwarding and go straight to voicemail | This usually means forwarding is set for "unreachable" but not "busy" calls. Contact your carrier to adjust the forwarding conditions. |
International Forwarding Issues | Delays or failed calls when forwarding overseas | International forwarding often has restrictions. Consider internet-based solutions like Skype or WhatsApp for international call management. |
When to Use Call Forwarding (Real-World Scenarios)
Business travel: Forward your work number to your personal iPhone when traveling. You'll avoid roaming charges while staying reachable for important calls.
Phone repairs: Your iPhone is getting fixed but you can't miss calls. Forward everything to a temporary device or family member's phone.
Team coverage: Customer service teams forward calls between shifts. Sales teams route leads to available representatives.
Vacation backup: Forward your work number to a colleague covering your responsibilities while you're away.
Privacy and Security Considerations
What you should know: When you forward calls, the receiving phone sees the original caller's number. Some carriers log forwarding activity in your account.
For sensitive calls: Consider Google Voice or similar services offering better privacy controls. They don't expose your main carrier details to third parties.
When forwarding to shared phones: Tell recipients about privacy expectations. They'll answer calls meant for you and might accidentally share sensitive information.

FAQs
Does call forwarding work when my iPhone is turned off?
Yes! Since call forwarding happens through your carrier's network, it works even when your iPhone is dead, turned off, or completely out of service.
Will people know their calls are being forwarded?
Usually no. Most carriers make forwarded calls appear normal to the caller. However, the person receiving the forwarded call will see the original caller's number.
Can I forward calls to multiple numbers at once?
Standard carrier call forwarding only works with one number at a time. For multiple numbers, consider Google Voice or ask your carrier about "simultaneous ring" features.
Why am I getting charged for forwarded calls?
You pay for the "leg" of the call from your number to the forwarding destination. If you forward to a long-distance or international number, you'll pay those rates even if the original caller is local.
How do I know if call forwarding is already active on my phone?
Dial *72# and press call. Your carrier will send a message showing your current forwarding status. You can also check your carrier's app or call customer service.
